1. A simple multifunctional water lens manufacturing method comprises the following steps:
a. material preparation
A purified water bottle, a latex film, a rubber band, a transfusion tube, a needle tube, scissors and hot melt adhesive;
b. manufacturing process
(1) Cutting a 5 cm-long cylindrical container barrel from the middle of a purified water bottle by using scissors, and trimming and flattening the edge (preventing puncturing a latex film);
(2) a section of infusion tube with the length of 30cm is cut off by scissors, and a flow rate regulator is reserved;
(3) a small hole with the diameter of 0.5cm is arranged in the center of the cylinder wall of the intercepted cylindrical container;
(4) one end of the infusion tube is arranged in the small hole, the infusion tube extends into the cylindrical container barrel by 5mm, and the connecting port is sealed by hot melt adhesive to prevent air leakage;

(6) injecting water into the cylindrical container barrel until the cylindrical container barrel and the infusion tube are filled with water, and the syringe is filled with half of the water;
(7) the latex film is sealed at the bottom of the transfusion tube.
Application method
The thickness and the concave-convex shape (based on the elasticity of the latex film) of the lens are adjusted by injecting water or pumping water by using the injector, so that the convex lens or the concave lens is simulated on one hand, and the focal length of the lens is changed on the other hand, thereby changing the action on light.
In order to observe experimental phenomena more clearly, the light path is presented, the water lens is placed in a transparent container, and a proper amount of smoke is added, so that the process of human eye object viewing can be simulated, and the adjustment of crystalline lens can be simulated. The two self-made simple water lenses can also be used for simulating the correction of myopia and hypermetropia.
It will be apparent to those skilled in the art that various changes and modifications may be made in the present invention without departing from the spirit and scope of the invention. Thus, if such modifications and variations of the present invention fall within the scope of the claims of the present invention and their equivalents, the present invention is also intended to include such modifications and variations.
